Myrmotherula iheringi

Often grouped with similarly plumaged species in the “grey antwren assemblage” (see M. axillaris). Geographical distribution and diagnosability of races requires re-examination; possibly more than one species involved#R. Recent description of taxon oreni as full species#R was based on relatively low levels of genetic, vocal and plumage difference, and also recommended race heteroptera for species rank; greater genetic distinctiveness of latter is mirrored by acoustic evidence, which suggests its song has rising notes (score at least 2) with a larger frequency range (at least 1). More detailed integrative review of all taxa needed. Three subspecies recognized.

Subspecies and Distribution
  • M. i. heteroptera Todd, 1927 – Purus Antwren – SW Amazonian Brazil (headwaters of R Juruá E to R Madeira).
  • M. i. oreni Miranda et al., 2013 – Bamboo Antwren – SE Peru (extreme S Ucayali, NE Cuzco, Madre de Dios, N Puno), SW Amazonian Brazil (S of R Purus in E Acre) and extreme NW Bolivia (W Pando).
  • M. i. iheringi E. Snethlage, 1914 – Ihering's Antwren – SC Amazonian Brazil (W bank of R Tapajós and along drainages of R Jiparaná and R Roosevelt S to Rondônia).
